Patent JP-S5522237-A (JP)
Title: Program selector device
Inventor: OOUCHI NOBUTOSHI
IPC: G11B27/00
Filed: 1978-07-30
Abstract: PURPOSE: To secure an assured extraction of the program with avoidance of troubles by giving exchanging and loading of a number of cassette tapes in which plural number of programs are arranged continuously and in sequence and then securing an automatic extraction of the desired program via the picture cards or the like.  
     CONSTITUTION: Record band 17 is procided at one side of tape outer case T, and record/reproduction head 18 is installed in correspondence to band 17. When drawing out the outer case, change-over switch 19 is turned toward the side where the count signal is recorded on band 17; while switch 19 is turned to the side where the count signal recorded on band 17 is transmitted to count means 12 when loading the outer case respectively. Accordingly, the degree of the tape run is registered at means 12 simultaneously with the device of the tape outer case. As a result, the tape loaded next time can be counted to the same position as the previous time even if the tape may be drawn out at any position. Thus the quick winding can be given to the tape in right or left direction by address signal F of picture card J, ensuring an assured extraction of the desired program.

Title: Sense amplifier
Inventor: SONEDA MITSUO
IPC: G11C11/34
Filed: 1986-04-24
Abstract: PURPOSE:To attain a high speed action by executing a latch action at a high speed by the resistance with a second sense amplifier part connected through the resistance to a bit line and continuously, executing the latch action with a first sense amplifier part based on the data after the latch. CONSTITUTION:The second sense amplifier part connected through the first and second bit lines BL1 and BL2 and resistances R1 and R2 senses DELTAVs which is the difference of the electric potential of the first and second bit lines BL1 and BL2 through the resistances R1 and R2. From the existence of the resistances R1 and R2 at the second sense amplifier part, the capacity of the bit line itself comes to be equivalently smaller from the view point of the second sense amplifier part, the shifting quantity of a charge with the bit lines BL1 and BL2 and inverters 21 and 22 of the second sense amplifier part is suppressed and a latch action can be executed at a high speed. By the large electric potential difference after being latched at a high speed by the second sense amplifier part, the control of the first sense amplifier part is not controlled by the electric potential on the way of the sensing and a high speed and secure latch action is obtained.

Title: Infrared transmission glass
Inventor: NOGAMI MASAYUKI
IPC: C03C4/10
Filed: 1984-05-09
Abstract: PURPOSE:An infrared-transmission glass material prepared by using ZnBr2, PbBr2 and TlBr2 at specific molar ratios. CONSTITUTION:ZnBr2, PbBr2 and TlBr2 are compounded at molar ratios falling within the region surrounded by the lines connecting the points A(45,0,55), B(35, 10,55), C(35,30,35), D(45,30,25), E(65,10,25), and F(65,0,35) in the triangular diagram representing the molar composition. The mixture is melted by heating in a crucible at about 250-700 deg.C in an atmosphere free from oxygen and water. The molten mixture is poured into a mold made of a metal, graphite, etc., and cooled to obtain a colorless transparent glass.

Title: Kerosene burning apparatus
Inventor: TOMITA HIDEO
IPC: F23D11/02
Filed: 1989-04-13
Abstract: PURPOSE:To prevent the flame holes from becoming red hot and the occurrence of flame lift even when the throttle ratio is made larger by providing the air chamber with a primary air control device. CONSTITUTION:The throttle ratio (TDR) is smaller, the evaporated gas generated in the evaporator 15 is ejected from the outlet 17 on account of the air supplied from the burning fan 24 to enter the mixing chamber 19 where it is mixed with the evaporating air and the primary air from the valve device 29 to become a premixed gas. The premixed gas elected from the flame holes 20 starts burning by means of an ignition plug 25, and the burning is promoted by the secondary air ejected from the air holes 22. If the TDR is greater, the primary air control hole 28 is closed by the valve device 29 to shut off the primary air. Therefore, the air supplied from the burning fan 24 is divided into two groups of the evaporating air and the secondary air. The evaporating air becomes the premixed gas by being mixed in the mixing chamber 5 with the evaporated gas generated in the evaporator 15. Because no primary air is supplied, the PA becomes small, preventing the flame holes from becoming red hot and the occurrence of flame lift.

Title: Horn
Inventor: KINOSHITA SHIYOUZOU
IPC: G10K11/02
Filed: 1981-06-19
Abstract: PURPOSE:To obtain a uniform directivity at a broad frequency range, by arranging under dispersion a plurality of cores of almost spindle shape at the inside of a conical horn. CONSTITUTION:The change in cross section can be formed into a prescribed shape such as exponential hyperbolic shape, by arranging under dispersion a plurality of spindle-shaped cores 1A at the inner circumference of a horn main body 1 of conical shape in matching with the radial direction of the horn main body 1. Thus, uniform directivity can be obtained independently of transversal and longitudinal directions at a broad frequency range, and further a broad band  characteristic as a horn of exponential and hyperbolic form can also be obtained. Since it is unnecessary to deform sound path unreasonably, a straight characteristic can be obtained without parasitic resonance.

Therefore, the temperature rise of the ventilating wind in the cover member 4 by the heat generated in the heat generation part can be suppressed, and the dimension of the ventilating fan can be reduced.

Title: X-ray mask
Inventor: YAMADA MASAO
IPC: G03F1/22
Filed: 1988-04-15
Abstract: PURPOSE:To reduce the degree of irregularity of the interval between a membrane and the surface to be exposed by a method wherein the adhering surface of the membrane of a ring-shaped supporting frame is inclined in the thinning direction of the supporting frame from the inner edge to the outer edge. CONSTITUTION:An X-ray mask is composed of ring-shaped supporting frames 10B and 22A, and a lightweight element material, the musk is also composed of a film-like membrane 12, which is adhered to one end face of the supporting frames 10B and 22A, and a heavy metal, and also it has an absorbing pattern 16 formed on the membrane 12. The adhering surface of the membrane 12 of the supporting frames 10B and 22A is inclined in the direction where the supporting frames 10B and 22A are thinned off from the inner edge to the outer edge. By this inclination, the substantial area of the membrane 12 opposing to the substance to be exposed becomes almost equal to the aperture area of the supporting frames 10B and 22A. Accordingly, the degree of inequality of the interval of both of the above-mentioned areas due to the presence of dust between the membrane 12 and the material to be exposed can be reduced.

Filed: 1980-07-10
Abstract: PURPOSE:To obtain a diaphragm whose annealing effect is suppressed, by forming the diaphragm, used for a speaker, etc., through using Mg-Al-Zr alloy containing 0.2-1.0% Zr. CONSTITUTION:This invention is an improved diaphragm for a speaker, etc., which is made of the alloy of Mg and Al, and the diaphragm is formed by using Mg-Al-Zr alloy containing 0.2-1.0% Zr. Normally, when the speaker driven, the generation of heat of a voice coil heats the diaphragm and when the driving is stopped, it is cooled naturally to decrease its Rockwell hardness by about 25% because of annealing effect. This invention, however, eliminates large variations in hardness only by adding a small amount of Zr, and the deterioration of frequency characteristics due to a secular change, specially, a limit frequency of high sound intensity reproduction is evaded.
